For new email accounts follow these steps:

1. In the Main Menu, select Tools and then Accounts

2. Click the Mail tab and select Add and then select Mail

3. You will then proceed to the Internet Connection Wizard where you will need to follow the steps as shown below (substituting your information). Remember to click Next after following each step.

Tip: Replace "yourdomain.tld" with your actual domain name i.e. ahcorporation.com (do not use "www" before domain name).

NOTE: You must use mail.yourdomain.com for the Incoming mail (POP3) server and mail.yourdomain.com for the Outgoing mail (SMTP) server (replacing "yourdomain.com" with your actual domain name in both cases.)

4. After clicking Finish, Outlook will automatically check the mailbox that you've just added and supply you with any errors if you've entered information that is incorrect. To manually request that it check email, simply click the "Send/Recv(Receive)" button. Assuming that you've entered the correct information and there's mail in the account you've just added, your messages should be downloaded. You will now need to go back and set up smtp authorization. To do this go to the Tools menu, click on Accounts, and select Mail.

5. To set up SMTP Authorization, click on the email account from the Mail tab, and click the "Properties" button.

6. Select the Servers tab, and place a check in the box titled "My server requires authentication"
.

7. Click the "Apply" button, then the "OK" button, and close out the remaining windows.
